Garmin MapSource - txt (tab delimited) (garmin_txt)

This is a textual format that contains nearly all of the information
contained in the MapSource™ main format, GDB.
This format also contains some computed values such as distances between
routepoints and trackpoints, speed, and course (heading).

The main goal of garmin_txt is to make aviation data more available. Because
MapSource™ supports only the export, GPSBabel gives you the possibility to
bring aviation data into MapSource™.

During the export with MapSource™, some fields are written using local settings
of MapSource™ and Windows. These include grid format, gps datum, distance and
temperature units, and the representation of date and time fields. GPSBabel
tries to read all items automatically. Problems with date and time format can
be solved with the 'date' and 'time' options.
